Patient & BP Monitor Repair and Calibration
Multi-parameter monitors and NIBP units drift long before they fail outright — and a monitor reading 6 mmHg high is more dangerous than one that has stopped completely. We repair and recalibrate every channel, then issue a certificate you can put in front of an inspector.
What we service
Bedside and transport monitors, vital-signs spot-check units and standalone NIBP machines, across all major manufacturers. If it measures a patient parameter, we can test it.
- Multi-parameter bedside monitors (theatre, ward, ICU)
- Vital-signs spot-check and transport monitors
- Standalone NIBP / blood pressure units
- SpO2 pulse oximeters and probes
- Fetal monitors and CTG units
Every channel tested, not just the one that failed
A monitor is several instruments in one housing, and they drift independently. A unit can hold perfect NIBP accuracy while its SpO2 channel reads three points high. We test each measurement path against reference equipment:
- NIBP — static pressure accuracy across the range, plus leak-rate and over-pressure cut-off checks
- SpO2 — saturation accuracy and pulse rate against a simulator
- ECG — amplitude, heart-rate accuracy and lead-off detection
- Temperature — probe accuracy at clinical set points
- Alarms — audible and visual alarm limits actually trigger where they should
Common faults we see
Most monitor call-outs are not catastrophic failures. The usual culprits are worn NIBP cuffs and hoses leaking pressure, SpO2 probes with broken internal wiring, flat internal batteries that make a monitor useless the moment it is unplugged, and accumulated drift that has never been checked because the device "seems fine". Cuffs and probes are consumables — we replace them rather than pretend a perished hose can be calibrated back into specification.
What you receive
A calibration certificate recording the readings taken before and after adjustment, the reference equipment used, and the date of the next recommended service — formatted for SAHPRA and ISO 13485 audits. If a device cannot be brought back into specification, we say so plainly and quote the replacement rather than issue a certificate it does not deserve.

Common questions
Patient monitor FAQs
Annually is the usual interval for clinical monitors, and it is what most inspectors expect to see documented. Devices in theatre or ICU, or any unit that has been dropped, repaired or is producing readings a clinician has questioned, should be checked sooner. We record a next-service date on every certificate so the interval is easy to track.
In most cases yes — our technicians bring reference equipment to you, which avoids taking a monitor out of service for transport. Where a fault needs workshop-level repair we collect the unit and return it tested and recalibrated.
That is exactly what calibration is for, and it is worth acting on. Drift is gradual and invisible — the monitor gives a confident reading that happens to be wrong. We test the NIBP channel against a reference, adjust it back into specification, and document the before and after readings so you have evidence of what changed.
Yes. Cuffs, hoses and probes are wear items rather than repairable parts, and a perished hose cannot be calibrated back into specification. We supply replacements for all major brands and can quote them alongside the service.
